3 Installing the Air Locker

Figure 7.

c Remove any sharp edges left behind by the modifications that

could break off and fall into the cavity.

c Make sure any grinding dust, filings or drill chips left behind by

cutting the drainage slots are completely cleaned out of the

housing.

c Check that the axle air vents are clear and working correctly.

3.2 Installing the Carrier Bearings

IMPORTANT:

GM’s 10 bolt, 30 spline axle assemblies were manufactured

using 1 of 2 different carrier bearing sizes. Measure the

outside diameter of one of the bearing cups that came off

of the original differential carrier.

Ø73.43mm [2.891”] = early model ‘small bearing’ version

Ø77.79mm [3.063”] = late model ‘large bearing’ version

If you have a small bearing axle then the carrier bearings

supplied with the Air Locker kit must be used

(Timken #LM102949-LM102911).

If you have a large bearing axle then the original bearings

will be reused (if they are of acceptable condition) or

replaced with new bearings of the same type.
